Auxiliary Detector Relays
You can use the base station’s vehicle detection circuits to operate an auxiliary
relay for a number of convenient uses (typically an external greeter or timer
module, but could also be used to operate a vehicle approach chime or other
device that is independent of the intercom system). Virtually any device that
can be activated by opening or closing a switch can be linked to vehicle
detection.
The relay terminals are numbered according to the vehicle detector they are
paired with. For example, R_NC, R1_NO, and R1_COM are paired with
Vehicle Detector 1.
There are several other sources from which to obtain the vehicle detector relay
signals. They are:
1. The 1_NO and 1_COM from Lane1 connector and 2_NO and 2_COM from
the Lane2 Connector
2. The 16 logical GPIOs can be configured via the basestation’s System Menu,
to pair up with the vehicle detectors for Lane1 or Lane2
